About

From bootstrapping in Romania to building fintech infrastructure in London.

Cristian Dan — Fractional CTO and startup founder

The Journey

First startup at 21 — built City365 from a hackathon win to an accelerator-backed company, pitching to Tim Draper while finishing my master's and working part-time to pay rent.

Moved to London and led mobile/frontend engineering at fast-paced startups: Zebra Fuel (logistics), Stint (gig economy), managing teams of 6+.

Co-founded Yayzy and wore every hat: raised $1.5M, built a team of 7, shipped Open Banking integrations with 2,500+ banks, got featured by Apple, Forbes, and TechCrunch.

Recently led a DeFi project (Elektrik Network) through V1 launch and agency-to-internal team migration.

What I do now: Fractional CTO, technical co-founder, or hands-on engineering — whatever gets your product shipped.

How I Work

Ship, then iterate

Perfect is the enemy of shipped

Own the outcome

Not just the code

Security by default

Not as an afterthought

Clear > clever

Maintainability wins

Outside Work

I clear my head with morning runs around London.
